What makes life coaching so powerful is the combination of 3 key elements:
1) (Who) help clients to discover and understand who they are.
2) (What) help clients to identify and clarify what they most want.
3) (How) help clients to create and develop strategies for how they will achieve their goals.
What I found with many years of that makes coaching so powerful, is the Who element. Goals (What) and strategies (How) are great, but unless integrated with the person (Who), they will take longer to accomplish, probably not be what the person really wants and not cause the level of happiness and fulfillment that are possible.
I will leave you with this quote from Lao Tzu “knowledge of self is the source of our abilities”.
